library: helper functions: implemented compatible library and objects wrappers.
+ based on work by jperkin (as well as slibtool's default wrapper functions).
+ generate verbose .la/.lo wrappers that match gnu libtool's output.
+ dependency_libs string is currently empty, to be added in a separate patch.
+ ordering of library_names is different, should (probably) not matter.
